The goat is most likely a reference to the curse that was placed on the Cubs by Billy Goat Tavern owner William Sianis during the 1945 World Series. Sianis' goat was denied entrance to the game and the Cubs lost the World Series.

No note was attached to the package Wednesday.

The curse has tried to be broken on numerous occasions over the last 67 years, but with no luck. The Cubs last won a World Series in 1908 -- the longest drought in professional sports.

The Cubs lost 101 games last year and are widely expected to finish in last place again this season in the National League Central.

The Cubs are in the midst of a 10-game homestand. Their game Wednesday against the Milwaukee Brewers was postponed because of rain.
